[0022] By adopting the above technical solution, rotating the handle 72 will drive the adjusting trapezoidal screw 71 to rotate, and under the action of the guide slide rod 74, it will drive the placement plate 2 to rise and fall, thereby adjusting the height of the device. It is convenient to use and has a practical structure.

[0023] Specifically, a stop 75 is fixedly connected above the guide slide rod 74.

[0024] By adopting the above technical solution, the stop 75 can easily limit the range of lifting and lowering.

[0025] Specifically, the stabilizing component 76 includes a mounting plate 761, mounting screws 762, a connecting plate 763, and a rotating screw suction cup 764. The mounting plate 761 is abutted against both sides of the base plate 1. The connecting plate 763 is fixedly connected to one side of the mounting plate 761. The rotating screw suction cup 764 is fixedly connected to one end of the connecting plate 763. The mounting screws 762 are installed at both ends of the mounting plate 761.

[0026] By adopting the above technical solution, the mounting plate 761 and mounting screws 762 facilitate the connection and fixation between the rotating screw suction cup 764 and the base plate 1. Then, the device is placed on the table and fixed by the rotating screw suction cup 764, so that the device can be stably placed on the table, thereby protecting the device and preventing it from being accidentally knocked off.

[0027] Specifically, threaded holes for mounting screws 762 are provided on both sides of the base plate 1.

[0031] In this embodiment, when in use: rotating the handle 72 will cause the adjusting trapezoidal screw 71 to rotate, which in turn will cause the placement plate 2 to rise or fall under the action of the guide slide 74, thereby adjusting the height of the device. It is convenient to use and has a practical structure. The mounting plate 761 and mounting screws 762 facilitate the connection and fixation between the rotating screw suction cup 764 and the base plate 1. Then, the device is placed on the table and fixed by rotating the screw suction cup 764, so that the device can be stably placed on the table, thereby protecting the device and preventing it from being accidentally dropped. This allows for convenient height adjustment of the device during use, and the structure is practical and allows the device to be stably placed on the table.

[0032] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the placement component 8 includes a support base 81, a placement base 82, and a stop 83.

[0033] By adopting the above technical solution, after the device is used, the measuring cylinder 5 is placed in the arc-shaped groove of the placement seat 82, so that the opening of the measuring cylinder 5 faces downward and fits against the stop seat 83, which makes it convenient to put the measuring cylinder 5 away for water control after use.

[0034] Specifically, a positioning frame 84 is fixedly connected to the upper part of the support base 81, a positioning screw 85 is threadedly connected to the middle of the positioning frame 84, a positioning plate 86 is rotatably connected to the lower part of the positioning screw 85 through a bearing, the positioning plate 86 and the positioning frame 84 are in close sliding connection, and a rotating block 87 is fixedly connected to the upper part of the positioning screw 85.

[0035] By adopting the above technical solution, after the measuring cylinder 5 is placed, the rotating block 87 is rotated, which drives the positioning screw 85 to rotate. The rotation of the positioning screw 85 will drive the positioning plate 86 to move down. Together with the protective pad below it, the measuring cylinder 5 is limited and fixed, which improves the stability of the placement and plays a protective role to prevent it from being knocked off.

[0036] Specifically, a limiting seat 88 is fixedly connected to one end of the base plate 1, and a collection box 89 is tightly inserted into the middle of the limiting seat 88.

[0037] By adopting the above technical solution, the limiting seat 88 facilitates the placement of the collection box 89, and the collection box 89 facilitates the collection of the remaining water.

[0038] Specifically, an arc-shaped groove is provided above the placement seat 82, and a flow groove is provided in the middle of the stop seat 83.

[0039] By adopting the above technical solution, the arc groove facilitates the placement of the measuring cylinder 5, and the flow groove facilitates the water to flow through the baffle 83.

[0040] In this embodiment, after the device is used, the measuring cylinder 5 is placed in the arc-shaped groove of the placement seat 82, with the opening of the measuring cylinder 5 facing downwards and in contact with the stop seat 83. This facilitates the draining and placement of the measuring cylinder 5 after use. After the measuring cylinder 5 is placed, the rotating block 87 is rotated, which drives the positioning screw 85 to rotate. The rotation of the positioning screw 85 will cause the positioning plate 86 to move downwards. Together with the protective pad below it, the measuring cylinder 5 is limited and fixed, improving the stability of the placement and providing protection to prevent it from being knocked off. The limiting seat 88 facilitates the placement of the collection box 89, and the collection box 89 facilitates the collection of the remaining water. This makes it convenient to drain and place the measuring cylinder 5 after cleaning when using the device.

[0041] The rotating screw suction cup 764 in this utility model is a previously disclosed technology, and the selected model is cwxp-002.

[0042] The structure and working principle of the measuring cylinder 5 in this utility model have been disclosed in a measuring cylinder holder with magnification function disclosed in Chinese patent application number 201720719570.5. Its working principle is that the measuring cylinder 5 is placed on the device for storage.

[0043] The working principle and usage process of this utility model are as follows: In use, the measuring cylinder 5 is placed on the limiting frame 4, with its lower part in contact with the soft pad 6 for protection. The height of the device can be easily adjusted using the adjusting component 7 to allow for easy observation by experimenters of different heights. The stabilizing component 76 securely places the device on the table, providing protection against accidental drops. After use, the measuring cylinder 5 is cleaned and placed on the placement component 8 for drainage. This structure also provides convenient limiting protection for the measuring cylinder 5. When using the adjusting component 7, rotating the handle 72 rotates the adjusting trapezoidal screw 71, which, under the action of the guide slide 74, raises and lowers the placement plate 2, thus adjusting the height of the device. It is convenient to use and has a practical structure. The mounting plate 761 and mounting screws 762 facilitate the connection and fixation between the rotating screw suction cup 764 and the base plate 1. Finally, the device is placed on the table. The device is secured by rotating the screw suction cup 764, allowing it to be stably placed on the table, thus protecting it from accidental drops. The device's height can be easily adjusted during use. Its practical structure ensures stable placement on the table. When using the placement component 8, after use, the measuring cylinder 5 is placed in the arc-shaped groove of the placement seat 82, with its opening facing downwards and in contact with the stop seat 83. This facilitates draining the measuring cylinder 5 after use. After the measuring cylinder 5 is placed, rotating the rotating block 87 causes the positioning screw 85 to rotate, which in turn moves the positioning plate 86 downwards. This, combined with the protective pad below, limits and fixes the measuring cylinder 5, improving stability and protecting it from being knocked off. The limiting seat 88 facilitates the placement of the collection box 89, which collects any remaining water, making it easy to drain the measuring cylinder 5 after cleaning.
